Lithium is a soft, silvery-white metal that is the lightest solid element. It was discovered in 1817 by Johan Arfvedson in Sweden and derives its name from the Greek word "lithos" meaning stone. Lithium has various applications including use in rechargeable lithium-ion batteries, as a mood-stabilizing drug, and as a coolant in nuclear reactors.

2.  Meaning
 “Lithos” which is Greek for “stone”
 Given this name because it was discovered in a stone
unlike other common Group 1 elements which were
found in plant sources
 Discovered
 By Johan Arfvedson in 1817
 In Stockholm, Sweden, during an analysis of petalite

3.  Solid at Room Temperature
 Lightest Solid Metal
 Soft and has a Silvery-White color
 Melting Point: 180.5 oC
 Boiling Point: 1342 oC
 Density: .53 g.cm-3 at 20 oC

4.  Many of its chemical and physical properties
are more similar to the properties of the
alkaline earth metals rather than the properties
of its own group.
 Major Isotopes
 Has 7 isotopes with mass numbers 5 to 11 but only 2
are stable: Li6 and Li7
 Has a high specific heat capacity
 3.58 J/gK

5.  Burns with a red flame but when burning
extremely well the flame turns a bright white
 It is the only common element that reacts with
nitrogen at room temperature

6.  Found in the Earth’s crust
 Abundance of 20 parts per million by weight or 60
parts per million by moles
 Highly reactive and does not occur freely in
nature
 Cost:
 $27 per 100 grams for Pure Lithium
 $9.50 per 100 grams for Bulk Lithium

7.  Used in rechargeable Lithium ion Batteries
 Also has various nuclear applications
 Used as a coolant in nuclear breeder reactors
 Is a source of Tritium
 Formed by bombarding Lithium with Neutrons

8.  Lithium Carbonate
 Used as a mood-stabilizing drug
 Lithium Chloride and Bromide
 Used as Desiccants
 Lithium Stearate
 Used as an all-purpose and high-temperature
Lubricant
